Bulletin issued at 04:02 HKT 20/Oct/2016

At 4 a.m. at the Hong Kong Observatory the air temperature was 25 degrees Celsius and the relative humidity 93 per cent.

Tropical Cyclone Haima will move across the northern part of Luzon and enter the South China Sea on Thursday morning. The Observatory will issue Standby Signal, No. 1 by then. According to the present forecast track, Haima will edge closer to the coast of Guangdong on Friday, and may skirt within 100 kilometers of Hong Kong, posing a threat to the territory. The weather is expected to deteriorate significantly on Friday. There will be frequent squalls and heavy rain. Seas will be rough with swells. Members of the public should remain vigilant and take all precautions as early as possible.

    Tropical Cyclone Warning

    Tropical Storm Sarika (1621) has weakened into a Tropical Depression with central pressure 998 hectopascals. At 190900 UTC, it was centred within 60 nautical miles of two one point eight degrees north (21.8 N) one zero seven point nine degrees east (107.9 E) and is forecast to move north at about 5 knots for the next 24 hours.

    The Hong Kong Observatory's tropical cyclone warnings for shipping are issued about one and a half hours after the time of observation. They incorporate additional information derived from surface and upper-air data and may therefore be slightly different from the real-time satellite or radar-based positions given in the hourly bulletins for public.

    While the forecast positions and track indicate the most likely future path of the tropical cyclone, they may deviate from the actual path taken by the storm.

Note

      

    1. From readings taken at various locations in Hong Kong during
the period 1987-2015, the background ambient gamma radiation
levels may vary between 0.06 and 0.30 microsievert per hour.

    2. The extent of health effects to a person as a result of
exposure to radiation is expressed by a physical quantity
called equivalent dose, in unit of sievert.  Protective
action may be required if there is an increase in the
ambient gamma dose rate above background such that the total
additional dose is expected to exceed 5000 microsieverts in
a relatively short period of time. For example, a dose of
5000 microsieverts may be reached when the ambient gamma
dose rate is 1000 microsieverts per hour (several thousand
times above background) and lasts for 5 hours.

    3. The readings of ambient gamma radiation level from
instrument are expressed in unit of gray, which is
numerically equal to the gamma dose expressed in sievert.
